太谷核不育小麦是我国特有的遗传资源。它雄性败育彻底 ,不育性稳定 ,异交结实率高 ,是一个非常难得的雄性不育材料 (邓景扬等 ,1 981 )。控制太谷核不育小麦不育性的显性基因 Ms2 (Ta 1 )位于 4D染色体短臂上 ,距离着丝点 31 .1 6个交换单位 (刘秉华等 ,1 986)。为了拓宽太谷 Taigu nuclear sterile wheat is China’s unique genetic resources. It is a male genital abortion, stable sterility, high diplomacy, is a very rare male sterile material (Deng Jingyang et al., 1981). The dominant gene Ms2 (Ta 1) that controls the sterility in Taigu nuclear sterile wheat is located on the short arm of chromosome 4D from 31.16 units of exchange (Liu Binghua et al., 1986). In order to broaden Taigu
